Abstract :
Carbon nanotubes (CNTs) are known for their excellent emission properties because of their own characteristics. This paper described the fabrication of a new planar field emission backlight unit (FE-BLU) with CNTs. The CNT cathodes were prepared by screen-printing on elaborate Ag electrodes and sealed into a prototype of 10-inch FE-BLU after CNTs had been chemical modified. The results showed that the CNT cathode had good field emission properties, with low turn-on electric field of 1.0 V/mum, the current density of 7.0 mA/cm2 at the electric field 3.0 V/mum, and high luminance brightness of 5300 cd/m2. Moreover, the CNT FE-BLU demonstrated a good performance of luminance brightness 3200 cd/m2 without significant degradation after 80 days.
